* Fix crown on NixOS
* no need to install libs, because there are none
* fix program name in usage message
* use the cargo provided by each buildPhase
* cargo update --offline can be used to reformat lockfiles
* document how to keep rust-toolchain.toml and etc/shell.nix in sync
* clarify comment about allowBuiltinFetchGit
* fix license
* clarify purpose of filterlock
* explain why crown must not use workspace dependencies
This completes the transition to compiling Servo with rust stable. Some
nightly-only features are still used when compiling the `script` and
`crown` crates, as well as for some style unit tests. These will likely
break with newer compiler versions, but `crown` can be disabled for them
conditionally. This is just the first step.
This has some caveats:
1. We need to disable setting up the special linker on Linux. The -Z
option isn't supported with stable rust so using this is out --
meanwhile we can't be sure that lld is installed on most systems.
2. `cargo fmt` still uses some unstable options, so we need to rely on
the unstable toolchain just for running `fmt`. The idea is to fix this
gradually.

This change makes rustup a requirement for building Servo with `./mach`
and switches to the newer `rust-toolchain.toml` format. The goal here is
to make mach builds more similar to non-mach builds.
- The new format allows listing the required components, removing some of
the complexity from our mach scripts.
- This means we must raise the required version of rustup to 1.23. The
current version is 1.26.
- We no longer wrap every call to cargo and rustc in "rustup run" calls
as both cargo and rustc will take care of installing and using all
necessary components specified in `rust-toolchain.toml` when run
inside the project directory.
